Abstract
The present invention relates to a kind of methods of loan pigmentation top sizing.It is mainly characterized by comprising: that sizing agent quality proportioning is polyvinyl alcohol: pigment 5: 1~15: 1；Pigment is calcium carbonate, 0.05~1 μm of average grain diameter, and partial size accounts for 95% or more in 2 μm of particles below；Being glued fluid solid content is 3%~10%；Resin added single side is 1~3g/m2；Good using the resulting pigmentation glue application layer transparency of the method, the loan after pigmentation is glued has good printability.
Description
Technical field
The invention belongs to field of papermaking, and in particular to a kind of method of loan pigmentation top sizing.
Background technique
Loan is mainly used for stamp, security, certificate, bill, trade mark, product description, anti-counterfeit package etc. [1].With
Epoch progress, people have requirements at the higher level to the printing effect of loan.The surface property of loan is to influence loan printing
One principal element of effect.
Top sizing and pigment application are to improve the common surface treatment method of page characteristic, and wherein top sizing is main
Effect be improve page surface strength, reduce printing when page hair and powder dropping the phenomenon that, sizing agent mainly have starch and its
Modified product, cellulose derivative, polyvinyl alcohol, synthetic latex etc.；Pigment application be mainly used for improve page surface performance and
Printing performance, coating are mainly made of pigment, adhesive, auxiliary agent and water.Pigmentation top sizing is a kind of between sizing and painting
Paper surface processing method between cloth can be effectively improved paper by being applied to paper surface after sizing agent is carried out pigmentation
Printing performance and appearance property, and have the characteristics that at low cost, effect is good.
Loan is the main material of security printing product, and loan contains the antifraud markers such as watermark, anti-false fiber, has table
Face particularity.Loan is surface-treated, need to pay special attention to that loan cannot be influenced to the covering of loan antifraud marker
Antifalse effect.General top sizing influences less the transparency of paper sizing layer, but is difficult to be effectively improved the print of page
Brushing effects, and conventional pigment application and pigmentation top sizing can significantly improve the printing adaptability of page, while improve paper
The opacity of page, pigment have covering to page.Therefore, conventional pigmentation top sizing will cover the water in loan
The antifraud markers such as print, anti-false fiber, to influence the antifalse effect of loan, document rarely has to be improved using pigmentation top sizing
The report of loan printing effect.
Summary of the invention
The purpose of the present invention is to provide a kind of method of loan pigmentation top sizing, this method is not influencing security
Under conditions of the antifalse effects such as paper watermark, anti-false fiber, improve the smoothness of loan, ink receptive, print gloss and
The performances such as color density improve the printability of loan.
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
1) firstly, polyvinyl alcohol is dispersed in water, is impregnated, (60~90 DEG C) dissolutions is then heated, solid content 5% is controlled
~10%.2) pigment is carried out it is fully dispersed, be prepared into solid content be 5%~25% dispersible pigment dispersion.
3) dispersible pigment dispersion is added in poly-vinyl alcohol solution under stiring and prepares glue application solution, add water to adjust glue application solution solid
Content is to 3%~10%.
4) pigmentation top sizing is carried out to loan, drying temperature is (105 ± 2) DEG C, and the page after sizing is through toning
Press polish after wet, rolling condition are 20~40kPa of pressure, 60~70 DEG C of temperature, obtain pigmentation top sizing loan.
The degree of polymerization of the step 1) polyvinyl alcohol is 1700~1800, and alcoholysis degree is 86~99%.
The pigment is calcium carbonate, 0.05~1 μm of average grain diameter, and partial size accounts for 95% or more in 2 μm of particles below.
The mass ratio of the glue application solution polyvinyl alcohol and pigment is 5: 1~15: 1.
The pigmentation top sizing uses scraper method top sizing, and roll-type top sizing or film transfer gage surface are applied
The methods of glue, resin added single side are 1~3g/m2。
The resulting pigmentation glue application layer transparency of the present invention is good, and transparent rate of descent is less than 10%, after pigmentation is glued
Loan smoothness improve, ink receptive and absorbability, print gloss, color density be obviously improved, and can effectively improve card
The printability of certificate paper.
Specific embodiment:
Embodiment 1:
1) firstly, polyvinyl alcohol 1788 to be slowly added into water and be sufficiently stirred, mixing speed 100rpm or so stops
30~60min is impregnated after stirring again, then under stiring, is heated to 60~90 DEG C of dissolutions, after being completely dissolved, water adjustment is added to contain admittedly
It measures to 10%.
It 2) is 0.95 μm by average grain diameter, and partial size is carried out in the powdered whiting pigment that 2 μm of particles below account for 95%
It is fully dispersed, it is prepared into the dispersible pigment dispersion that solid content is 10%.
3) calcium carbonate pigment dispersion liquid is added in poly-vinyl alcohol solution under stiring and prepares glue application solution, polyvinyl alcohol with
The mass ratio of pigment is 10: 1 plus water adjusts sizing fluid solid content to 5%.
4) to 70g/m2Loan carries out pigmentation top sizing, resin added 1.5g/m2, drying temperature is (105 ± 2) DEG C,
Page press polish after damping after sizing, rolling condition: temperature 50 C, pressure 30kPa obtain pigmentation top sizing security
Paper.
5) use pigmentation glue application layer transparency rate of descent made from the method for 6.9%, pigmentation top sizing security
The print gloss 45% of paper.
Embodiment 2:
1) firstly, polyvinyl alcohol 1788 to be slowly added into water and be sufficiently stirred, mixing speed 100rpm or so stops
30~60min is impregnated after stirring again, then under stiring, is heated to 60~90 DEG C of dissolutions, after being completely dissolved, water adjustment is added to contain admittedly
It measures to 10%.
2) the dispersing agent cetyl three for being 1% to pigment oven-dry weight under stiring, is sequentially added into a certain amount of water
